Easily done with a 555 timer circuit --
http://www.kpsec.freeuk.com/555timer.htm
I have an Innovative Train Tech church bell sound module that can be triggered many ways. After originally planning to have the church bells go off when a train enters a specific siding, I realize that is pretty unrealistic. I would now like the church bells to play on a regular basis, say every 15 minutes. The unit can be triggered with a momentary on push button and run for ~60 seconds, but I would like this to be automatic
Can anyone help me with a simple timer circuit that would control a relay or be directly hooked up to the sound module to trigger it the way I've described?
